Can you use compression fittings on steel brake lines?

Compression fittings can splice pieces or sections of steel brake line together to create a seal between the two sections. The pressure running through brake lines is extremely high. Compression fittings typically are not capable of withstanding this high amount of pressure.

Are brake line unions legal?

Contrary to popular belief it is NOT illegal to make a new section of brake line and splice it into a non-rusted section of your old brake, as long as you use automotive grade SAE double/inverted flare, SAE “bubble” flare and DIN Single Mushroom flare unions and fittings.

Are brass fittings safe for brake lines?

Compression fittings shouldn’t be used for joining brake lines together at all. Under no circumstances, other than maybe a quick trail repair, should a compression fitting be used for brake lines.

Are compression fittings reliable?

Although compression fittings are generally considered more reliable than threaded fittings, there are some potential problems. In general, compression fittings are not as resistant to vibration as soldered or welded fittings. Repeated bending may cause the ferrule to lose its grip on the tube.

Are compression fittings safe?

How much PSI is in a brake line?

Most of the metal brake lines burst around 15,000 psi. The typical full-lock operating pressures are 900–1,000psi (69 bar) with manual brakes and 1,400-pluspsi ( 96 bar) with power-assisted brakes.

What kind of fittings are on brake lines?

There are two basic types of flares used on OEM automotive brake systems throughout the world. The SAE/double (inverted/45degree) flare and the DIN/ISO bubble flare. We will refer to them as SAE or DIN flare. The most common is the SAE flare.
